This keeps popping up every couple of months. I was wondering when it is
going to appear again and there you are. :)

Here's a major reason: 99% of the kernels are built with
-m(arch|tune)=generic. Think distros.

Also, I am still waiting for a proof that CPU-optimized kernels have any
advantages compared to the =generic ones.

HTH.
